Photocatalytic degradation of phenol over visible light active ZnO/Ag2CO3/Ag2O nanocomposites heterojunction
In this paper, ZnO heterojunction with Ag2CO3/Ag2O mixed phase was synthesized by precipitation and phase transformation routes. The synthesized photocatalysts were characterized by X-ray diffraction (XRD), BET specific surface area, field emission scanning electron microscopy (FESEM), transmission...

| description | In this paper, ZnO heterojunction with Ag2CO3/Ag2O mixed phase was synthesized by precipitation and phase transformation routes. The synthesized photocatalysts were characterized by X-ray diffraction (XRD), BET specific surface area, field emission scanning electron microscopy (FESEM), transmission electron microscopy along with energy-dispersive X-ray (TEM-EDX), Fourier transform infrared (FTIR), UV-Vis-NIR spectrophotometer to reveal their phase, morphology, purity, and optical properties. The photocatalytic activity of the obtained nanocomposites was measured by the degradation of phenol under visible light irradiation. The results demonstrated that, the heterojunction mixed phase of Ag2CO3/Ag2O over ZnO surfaces has major effect on establishing the performance of the phenol photodegradation process. It can be noted that the Ag2O crystal’s growth over Ag2CO3 heterojunction on ZnO lattice, effectively facilitate charge transfer and suppress recombination of photogenerated electrons and holes, leading to highest impact phenol degradation. The synthesized photocatalyst displayed excellent properties, showing a potential industrial application for the treatment of phenolic wastewater. |
